The AULUMU C01 Hi-Per Titanium Alloy Watch Band targets Apple Watch owners seeking a durable metal option without the weight penalty. Built from aerospace-grade titanium alloy, the band weighs 63g while claiming to be 43% lighter and four times stronger than conventional metal bands.

A Diamond-Like Carbon coating adds another layer of protection, making the surface ten times harder and more resistant to everyday wear. The band uses CNC precision machining to achieve a seamless fit with Apple Watch cases, and an ultra-slim magnetic clasp with N52 magnets allows secure fastening with one-finger release.

Compatibility spans the Apple Watch Ultra series (49mm), Series 11 and 10 (46mm), Series 9 through 7 (45mm), Series 6 through 4 and SE (44mm), and Series 3 (42mm). The 195mm band fits wrist sizes from 145mm to 225mm. Two finishes are available: natural Titanium and Black.

The C01 retails for $199 and ships globally with free express delivery.

Our take

As a long-time Apple Watch Ultra user, I have tried many bands, and one of my favourites is still Apple's old stainless-steel Link Bracelet. It feels great and still fits the Ultra, but the steel finish never quite matches the titanium case when you look closely. There are plenty of titanium bands that match the Ultra better, yet many of them use bulky link attachments or lugs that stick out on both sides and, in my opinion, spoil the clean shape of the watch. That is why I like Apple's titanium mesh-style link bands: they avoid those protruding lugs and are very comfortable to wear. The Aulumu C01 band follows a similarly clean attachment approach and combines it with lightweight titanium and a fairly minimal design. On paper, that makes it a very interesting option I would seriously consider trying on an Apple Watch Ultra in the future.
